Be it known that L'Gfironnn H., Fons?" a citizen of the Uniteiivtates, residing at Chicago, in the. county of Cook. and Stats of iiinois, have invented Qertain new anni useful Improvements in Dish Wiissisyot which the following is a specification.

This appiication is a, iiii'ision of my pending application Serial No.

The invention of this application to metsii wnssis and mors pnrtinuiarij; oi

that typs characterized by the empioymsnt of a disk body portion ussooiateti with t iisd rim or telly pnrtion adapted to rsf-sive :i demountabie rim sind has for its primary oiijoct a strengthening or" the disk body against deforn'isition by radiali or interni shocks incident to use. ri`his @hiaat is :ittained by tirs provision of raar suppnrt 0i the disk adjacent the huh portion where such strains are greatest..

it has been proposed to strengthnn the disk body of this type ot' Wheel by Qnipioying :i tapered disk oi gi'satest thirkness :it l its center and graduaiiy decreasing drifts ness towards its periphery; itis@ in; the onipioynient of 'radizii ribs 0i greatest thick ness arijii'cent th@ huh; also oy radiali timings or corrngfntons.

claim:

l, ln a. disk wheel, the ,:ornbination with a forwardly conca-ve disk body portion, of a rigid rear support for the disk adjacent the hub.

2. ln a disk wheel` the combinationv withn :forwardly concave disk body portion, oi a .rigid rear support for the disk, said support orining a part of the hub.

5, in a disk wheel, the. combination with a forwardly concave disk body portion, of. a. rigid rear support for the deepest portion thereof, said support fixedly associated with the hub. ,p i

4.. in a disk wheel, the combination with the disk body portion, of a rigid rear support therefor, said su sport consisting of a plate iifiedly secured to the hub.

in a disk wheel, the combination with Vthe forwardly concave disk body ptn-tion` of ineens lixedly associated with the hub at the rear oi the disk 'for supporting the. disk .iedially 6. ln a disk wheel, the combination with a disk body portion haring a Irearwardly extending; shoulder' at a distance troni the hub, .t' a plat-e ikedly secured to hub at the rear of the disk and underlying the shoulder to provice a radial rear support therefor.

7. ln a disk wheel, the combination with a disk body portion forwardly concave and provided with a bend or shoulder, of a plate ixedly secured to the hub and bearing against the shoulder to form a. support-there for.

Q. .lin a disk wheel. the combination with a. disk body portion forwardly concave and provided with a bend or shoulder, ot a pia-te :tixedly secured to the hub and underlying to detorining mesmo portion, the disk forwardly concave, the niay ferial of the disk extending forwardly aci-- jacent the periphery of'the hub plate to bear thereag'ainst. n M

ll. A steel disk wheel comprising` a hub portion, a medial disk portion, and a folly portion, the materialot the disk extending forwardly adjacent the periphery of the hub plate to bear thereon and again inwardly adjacent the hub proper to form a bearing thereon.
